Tungsten Disilicide Hmoov

Tungsten Disilicide Powder Description

Tungsten silicide (WSi2) yog ib qho inorganic compound, silicide ntawm tungsten. Nws yog cov khoom siv hluav taws xob ua hluav taws xob ceramic.

Tungsten silicide hmoov feem ntau tam sim ntawd muaj nyob rau hauv ntau ntim. Ultra siab purity, siab purity, submicron thiab nanopowder cov ntaub ntawv yuav raug txiav txim siab.

Tungsten silicide yog siv nyob rau hauv microelectronics raws li cov ntaub ntawv sib cuag, nrog resistivity 60-80 μΩ cm; nws tsim ntawm 1000 degree. Nws yog feem ntau siv los ua shunt hla cov kab polysilicon kom lawv cov conductivity thiab nce cov teeb liab ceev. Tungsten silicide txheej tuaj yeem npaj los ntawm cov tshuaj vapor deposition, xws li siv monosilane lossis dichlorosilane nrog tungsten hexafluoride ua cov pa roj. Cov zaj duab xis deposited yog non-stoichiometric, thiab yuav tsum tau annealing hloov mus rau ntau conductive stoichiometric daim ntawv. Tungsten silicide yog hloov pauv rau yav dhau los tungsten zaj duab xis. Tungsten silicide kuj tseem siv los ua ib txheej txheej ntawm silicon thiab lwm yam hlau, xws li tungsten.

Tungsten silicide kuj tseem muaj txiaj ntsig rau kev siv hauv microelectromechanical systems, qhov uas nws feem ntau yog siv los ua nyias zaj duab xis rau fabrication ntawm microscale circuits. Rau cov laj thawj zoo li no, cov yeeb yaj kiab ntawm tungsten silicide tuaj yeem ua cov plasma-etched siv xws li nitrogen trifluoride gas.

WSi2 ua tau zoo nyob rau hauv daim ntaub ntawv raws li oxidation-resistant coatings. Tshwj xeeb, nyob rau hauv zoo sib xws rau Molybdenum disilicide, MoSi2, lub siab emissivity ntawm tungsten disilicide ua rau cov khoom no txaus nyiam rau kub kub radiative txias, nrog rau kev cuam tshuam nyob rau hauv tshav kub shields.
